Abstract

The invention discloses a chemical heat regeneration type diesel engine, belongs to the field of internal combustion engines, and solves the problems of lower efficiency and higher oil consumption in a traditional diesel engine. The chemical heat regeneration type diesel engine imitates working principles of a chemical heat regeneration type aloof ramjet and a chemical heat regeneration circulating gas turbine; and diesel is sprayed into a cylinder for burning after finishing the chemical heat regeneration process. When the engine is operated, the diesel flows out from an oil tank to supercharge to form high-pressure diesel after filtration and flow adjustment; the high-pressure diesel flows into a spiral cooling channel to absorb heat generated by burning of a fuel in the cylinder and dispersed to the wall surface of the cylinder; the chemical cracking is generated when protecting the wall surface to generate one part of gaseous micromolecule products; a switching valve is switched to a thermal fuel oil way; high-temperature cracking gas and non-cracked diesel steam enter a gaseous fuel nozzle by the switching valve, and then are sprayed into the cylinder for burning; when the engine is started, as a temperature field is not built, the diesel is still in a liquid state before entering the cylinder; the switching valve is switched to a cold fuel oil way; and the diesel is sprayed into the cylinder after being atomized by a liquid fuel nozzle.

Description

technical field [0001] The invention belongs to the field of internal combustion engines. Background technique [0002] The internal combustion engine is currently the most commonly used form of power, and its exhaust gas is one of the important reasons for the greenhouse effect and air pollution. Among them, diesel engines widely used in trucks, buses, ships, tractors and railway locomotives are regarded by the public as "accomplices" of smog due to their low efficiency and substandard emissions in daily use. At the same time, the ever-increasing demand for oil consumption not only increases the environmental burden of our country, but also increases the international political and military pressure to maintain oil trade. Therefore, it is extremely urgent to improve the efficiency of diesel engines and reduce fuel consumption and exhaust emissions. [0003] As we all know, except for a limited part of the heat of internal combustion engine fuel combustion being converted ...
